Ok was driving heard a loud clunking, pulled over got towed home. Lifted car axle piece where it attaches to the back of the brake drum assembly is snapped in half? WTF anyone else have this problem??? '72 240Z L24

took the 4 bolts out of the axle shaft and where it meets the piece I broke,, put penetrating oil on it cause i cant get it apart.

is this a hard fix?

Sounds like a stub axle. You can replace this with a used 280 stub axle (stronger) but either way the strut comes off (you can leave the control arm on) and have someone press out the axle stub then have them press in a replacement stub axle. Good time to replace the wheel bearings and seals.

Might want to do both while the car is up on jackstands....
